    摘要： A flip chip-type nitride semiconductor light emitting diode includes a light transmittance substrate, an n-type nitride semiconductor layer, an active layer, a p-type nitride semiconductor layer and a mesh-type DBR reflecting layer. The mesh-type DBR reflecting layer has a plurality of open regions. The mesh-type DBR reflecting layer is composed of first and second nitride layers having different Al content. The first and second nitride layers are alternately stacked several times to form the mesh-type DBR reflecting layer. An ohmic contact layer is formed on the mesh-type DBR reflecting layer and on the p-type nitride semiconductor layer.

    摘要： The present invention relates to a process for preparing a beta-keto ester compound of formula (1), which is an intermediate for the synthesis of quinolone antibiotics. Particularly, the present invention is characterized by the reaction of an organo nitrile compound with a salt of mono-alkyl malonate in the presence of metal salt, and so the reaction is easy to control due to its endothermic nature, and is devoid of lachrymatory reagents with excellent reproducibility. Subsequent in situ hydrolysis in the presence of aqueous acid solution provided the compound of formula (1).

    摘要： An image forming apparatus and a fixing unit thereof are disclosed. The fixing unit includes a heating roller, a press roller mounted in close contact with the heating roller to apply heat and pressure to the printable medium with the heating roller, a press lever to press the press roller toward the heating roller, a press spring connected to the press lever, a release device to operate the press lever to release pressing force exerted on the press roller, and a power conversion device to transmit driving power generated from a main driving source to drive the heating roller to the release device. Accordingly, since the press lever pressing the press roller to closely contact the heating roller can be operated by the driving power of the main driving source, the jammed printable medium can be easily removed.
